Product Description

Bend Test on Plates, Pipes, and Bars

The bend test evaluates a material's ductility and resistance to cracking during deformation. It is commonly used to assess metal strength and identify surface cracks.

Key Features:

• Determines maximum bending strength.
• Reveals surface cracks and irregularities.
• Simple and quick procedure.

Test Procedure:

• The specimen is bent using a standard-sized mandrel to the required internal angle.
• After bending, the convex surface is inspected for cracks or surface flaws.

Failure Criteria:

• Complete fracture indicates test failure.
• Cracks visible to the unaided eye on the convex surface determine the material's performance.
• Cracks within one thickness of the specimen's edge are not considered a failure.
• Corner cracks are disregarded unless exceeding the specified size in product standards.

This method effectively verifies material flexibility and structural integrity under stress.
